John Punin announced the Log Markup Language (LOGML), an XML vocabulary designed for "mining data that has been collected from web server logfiles."

"We also gather the client activity in a web site as a subgraph of the web site graph. This subgraph can be used to get better understanding of general user activity in the web site."
